Purified proteins are required for many proteomics applications such as X-ray crystallography, NMR, mass spec, and in vitro biochemical assays. Proteins can be isolated from tissue or, more often, by their overexpression in an organism, like bacteria, yeast, or mammalian cells in culture.
This application note focuses on two challenging areas for nanoparticles: reliable, rapid scale-...

The proper selection and installation of equipment for your carrier gas system will help to ensure that you obtain the best possible performance from your GC instrument. A properly installed system and operation will pay for itself in added column lifetime, minimum system downtime, and better analytical results. Remember, doing it right the first time is less expensive than doing it over.
Sterility testing of final drug products is a mandatory release test. Traditional methods such as membrane filtration require a minimum incubation time of 14 days. This extended time to result delays product release and increases storage costs. Download this white paper and learn how to achieve results in just 5 days!
This new application note demonstrates the utility of the Chromatrap® ChIP-seq kit to elucidate the genome-wide binding patterns of nuclear receptor binding events in human adenocarcinoma cells; highlighting the fast multiplex capability alongside massively parallel NGS.
Ion chromatography (IC) is evolving to meet the analytical demands for more rapid analyses using significantly smaller sample volumes. Sub-5 minute analysis times and sub-ul sample volumes are now becoming available for some applications, along with a number of improved detectors. To take full advantage of these changes it is essential that sensitivity and reproducibility are maintained. The purity of the water used has a key role to play.
Ion chromatography (IC) is a form of liquid chromatography that is used to separate atomic or molecular ions for qualitative or quantitative analysis. As scientists demand ever more rapid analyses with smaller sample volumes, ultrapure water plays a key role in maintaining the sensitivity and reproducibility of IC applications.
Thousands of scientists around the world are making use of cutting edge technologies every day in order to push the boundaries of what we thought possible, furthering our understanding of the world around us. This dedicated pursuit of knowledge rests upon the shoulders of advances in the development of analytical instrumentation.
In this report, apoptosis was induced in HL60 cells with daunorubicin, a DNA-intercalating agent which inhibits DNA and RNA synthesis and is used as a treatment for acute myeloid leukemia (AML). HL60 cells were exposed to a time course of daunorubucin treatment.
The ImageStream® imaging flow cytometry platform was used to study the mechanism of action of Rituximab (RTX). RTX is a therapeutic monoclonal antibody directed against CD20 for the treatment of Non-Hodgkin’s lymphoma.
Increasing the number of samples which can be run simultaneously is desirable for high content analysis and screening applications. To increase sample throughput, the fluorescent cell barcoding method previously reported by Krutzik & Nolan has been adapted for the ImageStream®.
Many assays for immune function require imaging, but immune cells present significant challenges to image-based analysis due to their rarity and the need for simultaneous multispectral immunophenotyping, making statistically robust quantification difficult.
Gold Nanorods (AuNR) hold great promise for biomedical imaging. AuNRs have very strong absorption peaks in the visible and near-infrared region due to a plasmonic effect; the aspect ratio of the AuNR directly determines the wavelength of the peak.
Shared facilities, or common equipment rooms shared by several individual laboratories, often result in a laboratory having a number of unique users with varying levels of centrifuge experience using floor-standing ultracentrifuges and high-performance centrifuges.
Floor-standing ultracentrifuges and high-performance centrifuges are vital to many bioproduction processes. Instruments are run in Good Manufacturing Practice (GMP) environments, and must support compliance with these regulations.
This whitepaper reviews the causes of the three major allergic reactions to single-use glove products in Life Sciences environments, their symptoms, and glove solutions that are available to help prevent adverse reactions.
ChIP is a commonly used immunprecipitation technique for mapping the DNA-protein interactions in cells which are crucial for correct gene regulation. In a ChIP assay DNA-protein complexes (Chromatin) are selectively immunoprecipitated using antibodies directed against the protein of interest and the resulting fractions treated to separate the DNA and protein components.
